  • calculusxy
Yeah I am completely fine with that. Since no one was coming that's why I gave the second question.
Vocaloid
  • Vocaloid
ok, |dw:1443916995474:dw| with me so far?
calculusxy
  • calculusxy
yes
Vocaloid
  • Vocaloid
now we just set them equal to each other and solve for a
calculusxy
  • calculusxy
oh okay give me a moment to do this
Jhannybean
  • Jhannybean
Ah, I didn't realize you meant \(x=a\)

Vocaloid
  • Vocaloid
oh whoops, let me know when you're ready to keep going
calculusxy
  • calculusxy
i don't understand how to solve this actually
Vocaloid
  • Vocaloid
well, do you understand what I've written so far, or would you like a bit of explanation? :)
calculusxy
  • calculusxy
i understand what you wrote for the first box |dw:1443917401267:dw|
Vocaloid
  • Vocaloid
oh, ok, let's start from there |dw:1443917460459:dw|

Vocaloid
  • Vocaloid
|dw:1443917591847:dw|
Vocaloid
  • Vocaloid
does that make it a bit more clear?
calculusxy
  • calculusxy
yes i understand
Vocaloid
  • Vocaloid
ok, now we set these two values equal to each other|dw:1443917693138:dw|

calculusxy
  • calculusxy
no i don't understand this
Vocaloid
  • Vocaloid
remember foil?
calculusxy
  • calculusxy
we would use foil for (a - 2)^2 ?
Vocaloid
  • Vocaloid
yes!
calculusxy
  • calculusxy
okay
Vocaloid
  • Vocaloid
(a-2)^2 = a^2 - 4a + 4, using foil (you can verify if you'd like on your own)
calculusxy
  • calculusxy
i got the same answer
Vocaloid
  • Vocaloid
good, ready to keep going?
calculusxy
  • calculusxy
yes
Vocaloid

calculusxy
  • calculusxy
yeah wouldn't it be like the distributive property and making the numbers inside the parenthesis opposite?
Vocaloid
  • Vocaloid
yup
calculusxy
  • calculusxy
do we simplify it?
Vocaloid
  • Vocaloid
yeah, you can combine like terms
calculusxy
  • calculusxy
like from \[a^2 - 4a + 4 - a +2 \implies a^2 - 5a + 6\]
Vocaloid
  • Vocaloid
yup!
Vocaloid
  • Vocaloid
that gives us:
calculusxy
  • calculusxy
\[a - 2 = a^2 - 5a + 6\]
